[squid] invalid argument error

[rcktboy]

From time to time mostly here on the forum I get a "invalid argument" error from the proxy.
This happend after typing a new post or replay or when I try to search for something.
If I then go a page back and try to send again It works like normal.

The proxy is running transparent, Hard disk cache size is set to "0" and Hard disk cache system to "null"

Not that's anything big, but it would be nice to have this error not show anymore.

Attached part of the error page, partly dutch…

Just figured out that turning on the option to resolve DNS v4 first seems to solve this issue… (on the squid general settings tab).
